Low-Gravity Experiments: Shear Testing Takes a Nose Dive
A major challenge to making celestial soil mechanics viable is to re-engineer the profession's toolkit to provide geotechnical solutions without the luxury of ex-situ and in-situ testing as we know them...

Eyes in the Heavens: Satellite Technologies in Remote Site Monitoring
Installation and maintenance of instrumentation to monitor geotechnical projects in remote locales is usually more challenging than sites in urban areas for both technical and logistical reasons. In most...

When Old Meets New: Railway Geotechnics and Remote Sensing
Railroad track, like any other built structure, relies on a foundation of geomaterials for support. In its most basal form, the railway track is quite simple: steel load-bearing members (rails) supported...

Railway Geotechnical Asset Management in Great Britain: How Modern-Day Techniques Help Monitor Railway Infrastructure Dating to the 1800s
This article discusses asset management, risk management, and earthworks failures as experienced by Network Rail (NR), the owner, operator, and asset manager of the majority of the rail network of Great...

All About ISSMGE: An Interview with Leaders of the International Society for Soil Mechanics and Geotechnical Engineering
This article summarizes key discussions from an interview of a select group of International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) leaders, conducted by a small group of students...

The Wait Is Over…DIGGS Is Here!
The roll-out of Data Interchange for Geotechnical and GeoEnvironmental Specialists (DIGGS) has started, and the Ohio DOT (ODOT) has already announced that it will be required beginning January 2018. This...

The Case for Tolerable Risk Guidelines to Manage Flood Risk: Nature Bats Last
Since ancient times, people have used levees to reduce flood risk. We have built over 30,000 miles of levees in the U.S., largely on the belief that levies will unconditionally protect people who live...

Connecting Faculty in Geotechnical Engineering: Thriving in a Networked World
A robust social network, defined as a group of individuals and organizations with career-related and/or personal relationships with one another, is essential for operating successfully in today's business...

NSF Workshop on Geotechnical Fundamentals: How Researchers Can Contribute to Today's Real-World Challenges
A 2 ½ day National Science Foundation (NSF)-sponsored Workshop (Award No. CMMI-1248053) was held in July 2016 at the NSF headquarters in Arlington, VA. The Workshop focused on fundamental principles that...

Open Pit Geotechnics: Designing Slopes for a Very Deep Hole
For most hard rock surface mining operations, the development of an open pit is required to extract the ore resource. In designing an open pit, the challenge is to develop the most cost-effective pit slopes...

Where Geosynthetics Meet Mining Geotechnics: Part of the Mining Engineer's Toolbox
From enhancing stability to providing environmental containment, geosynthetic materials play an important role in mining projects and geotechnics in general. While often overlooked, advancements in geosynthetic...

Claims against Geotechnical Engineers: Getting it Right in the Midst of Uncertainty
Geotechnical engineering is one of engineering's riskiest professions, prone to litigation due to the inherent uncertainty associated with characterizing the subsurface. Site investigations rarely provide...

The Uselessness of Elephants in Compacting Fill
This article is based on an article that was originally published in the August 1967 Canadian Geotechnical Journal (Vol. IV, Number 3)....

Military Geotechnics in the Ancient World: Geo-Innovating the Hard Way
The technical expertise that is now part of geotechnical engineering was of paramount importance in the ancient worlds. This is because before, but also after, the invention of siege equipment, nearly...

Remote Sensing: A New Revolution in Geotechnical Engineering
Remote sensing in the form of satellite imagery has become part of our everyday life—from displaying boring locations at a job site to the various mapping apps on our smart phones that help us get there....

Geotechnical Aspects of Pavements: There's More to Roads than Asphalt and Concrete!
When you jump on the highway to make that commute to work, do you think much about what's under the surface you ride on? Pavements are layered systems designed to provide a strong structure to support...

Geotechnical Instrumentation for Roadways: Shifting from Manual to Automated
Geotechnical instruments, including inclinometers, piezometers, settlement plates, etc., have long been used during and after construction to monitor performance of transportation infrastructure, including...

What Does the Case Law Say? Geotechnical Risk on Design-Build Projects
The growth of design-build (DB) contracting, particularly on public-sector civil projects, has generated a great deal of industry discussion over the age-old question of who should bear the risk of unforeseen...
